    keyword=veto VH16 high voltage problem

    HV channel for vertical veto counter #16 did not come up when we were
    turning on veto HV . Looks like the ramp-up speed for this channel is set too
    high. I could not set it lower - it is already at the minimum. So I ramped
    the voltage manualy - started from 1000V and then did several 100V steps
    reaching its setting of 1505V
